I don't think that disabling 'deepscreen' is a good idea as it may allow other viruses, etc through.I used a combination of Kaje and ltbennett solutions (both on page 1) without looking at this forum and it all works fine. Although it was an extremely annoying and time consuming process working it out. I can see why people would just change AV instead.

i just right click on the avast icon and click stop all access protection then download the file with np

This does not work for me - Avast erased the trainer completely and said don't worry, we fixed everything...Reinstalled the trainer and shut off Avast for 10 min while DLing trainer; then trying to run any trainer for any program gets that trainer deleted as well...Dumping them. They do provide a way to "report" a false positive, but it's a form, and needs exact details, and who the hell do they think they are DELETING programs without asking? Morons is what.

2/14/14Avast sent me a Valentine and DELETED the entire trainer, so Not Fixed.

I use Avast on all my computers. I had Kaspersky and I have tried Norton, Avast just works the best I think. And I have had 0 problems with it so far, except for the starbound trainer. I had to add exceptions for that trainer and that trainer only.

You may be talking about the paid version. Mine was the free, and It erased **all** CH files I tried to run without asking first. I just downloaded and installed AVG free antivirus, DL'd the Trainer Manager and it is all good now, no interference.Just a short caution - when trying to DL AVG's FREE version, be very careful, the link is not easy to find and they put upgrades and suggestions in your way. It installed quickly, took a long time for the first scan, and is, I assume, working ok.
